  • Patent number: 7115792
    Abstract: The present invention is a scar-reducing plaster and a method for preparing scar-reducing plasters. The scar-reducing plasters comprise a backing film comprising an air- and water vapor-pervious and water-impervious polymer layer, and a breathable and adhesive polyurethane xerogel matrix layer that coats the backing film. The polyurethane xerogel matrix layer includes a central scar contact region and an edge region, wherein the scar contact region merges with the edge region and the thickness of the edge region decreases from the scar contact region to a thickness of from 5 to 150 ?m at the edge of the polyurethane xerogel matrix layer. The scar-reducing plasters of the present invention have a reduced tendency to peel off during normal use.

  • Patent number: 4321137
    Abstract: An apparatus for processing liquids such as water or the like by means of a reverse osmosis device has a main pump which provides an entrance pressure to the reverse osmosis device in connection with a throttle. In order to avoid any losses of energy, another pump is connected to the main pump. Via a rigid shaft, a turbine is connected to the other pump which turbine receives the high pressure located in the concentrate and releases it to the other pump.
